Target exams
Station brief
Format. Communication station, approximately 7–10 minutes active time after reading. You are the psychiatry registrar in the old-age outpatient clinic. [1]
Candidate instructions. Explain late-life generalised anxiety disorder in plain language; outline CBT and SSRI treatment; explain why long-term benzodiazepines are risky in older adults and how a slow taper works; mention blood sodium checks; safety-net for worsening mood or suicidal thoughts; check understanding. Examiner plays the patient; a second role-player may be the daughter. [2][3]
Candidate scenario
Your patient has multi-domain worry for nine months, avoidance of shopping, and nightly diazepam for years. Plan: late-life adapted CBT plus escitalopram 5 mg orally daily with slow titration, early sodium check, and gradual diazepam taper. The daughter fears “addiction to antidepressants” and wants more diazepam instead. [3][5]
Marking domains
- Empathy, structure, and shared agenda with patient and daughter
- Accurate plain-language explanation of late-life GAD
- Clear CBT + SSRI plan with start-low philosophy
- Benzodiazepine risks and taper rationale (falls/cognition)
- Sodium monitoring and when to seek help
- Suicide/mood safety-netting without scaremongering
- Checks understanding / teach-back [2][4][5][6]
Reveal assessor key
Open and agenda-set. Greet both; ask main worries first (fear of “happy pills,” needing diazepam to sleep, becoming a burden). Name time available. [1]
Explain illness. “What you describe is generalised anxiety disorder — a treatable condition where worry becomes hard to switch off and starts limiting life, such as avoiding shopping. It is more than normal caution with age, and it often travels with poor sleep and muscle tension. Many older adults improve with the right psychological therapy and, when needed, carefully chosen medication.”[1][2]
Explain CBT. CBT is a practical talking treatment that teaches skills to notice unhelpful worry cycles, test fearful predictions, relax the body, and gradually rebuild avoided activities. Trials in older adults show it can help late-life GAD, including in primary-care settings.[2]
Explain SSRI. An SSRI such as escitalopram can reduce anxiety. We start at a low dose (for example 5 mg daily) and increase only if needed. It is not a sedative “knock-out tablet.” We check blood sodium because older adults, especially on fluid tablets, can rarely develop low sodium — contact us for confusion, severe unsteadiness, or collapse.[3][4]
Benzodiazepine plan. Nightly diazepam can help short-term but long-term use in older people raises falls and memory concerns; specialist guidance treats many benzodiazepines as medicines to avoid for long-term use when safer options exist. We will reduce it slowly so you are not left suddenly without cover, while CBT and the SSRI take effect — not an abrupt stop.[5]
Safety-net. If low mood, hopelessness, or thoughts of wanting to die appear, contact us or emergency services the same day. Older adults can be at higher risk of completed suicide, so we take this seriously and make a clear plan.[6]
Close. Summarise, teach-back, written plan, blood-test timing, psychology appointment, crisis contacts, invite questions. [1]
